Question

In a resonance tube experiment when the tube is filled with water up to a height of $17.0 cm,$ from bottom, it resonates with a given tuning fork. When the water level is raised the next resonance with the same tuning fork occurs at a height of $24.5 cm .$ If the velocity of sound in air is $330 m s^{- 1},$ the tuning fork frequency is :

Options:

Answer:

A

Solution:

$\frac{λ}{2} = 24.5 - 17 = 7.5 cm$

$f = \frac{V}{λ}$

$= \frac{330 \times 100}{15} = 2200 Hz$

λ 2 = 24 . 5 - 17 = 7 . 5 cm f = V λ = 330 × 100 15 = 2200 Hz
